[0002] Currently, washing machines with detachable pulsators are available on the market. The advantage of a detachable pulsator is that users can disassemble it without tools to clean the washing machine. For example, TCL's detachable pulsator is locked by axial fixation; non-detachable pulsators are fixed by bolts to the inserts (lock cylinder). Therefore, detachable means that the pulsator can be easily removed without tools, making it convenient for users to clean. Summary of the Invention

[0046] Example

[0047] <Overall Layout>

[0048] As shown in Figure 1, the impeller device provided in this embodiment includes an impeller shaft 1, an impeller assembly, and a fixing assembly; a limiting key is formed near the end of the impeller shaft 1 for limiting the impeller shaft 1; the impeller assembly has an impeller and an insert; the impeller includes an impeller body 22 and an impeller plate 21, the impeller body 22 is circumferentially disposed on the impeller plate 21 for washing clothes; the impeller plate 21 is used for connection with other components; the insert 3 is detachably disposed at the bottom of the impeller plate 21 and circumferentially rotatably connected to the impeller shaft 1, preferably the insert 3 has a keyway formed at its center and, through cooperation with the limiting key, provides a function for the impeller shaft 1. Radial and circumferential limiting functions enable circumferential rotational connection between the impeller shaft 1 and the impeller assembly; the fixed assembly has a receiving member 4 and a limiting member; the top of the receiving member 4 has a supporting rib and is connected to one end of the limiting member through an elastic member, and the limiting member can move relative to the supporting rib under the action of external force; the bottom of the receiving member 4 is detachably connected to the insert 3; a first through hole 46 is formed at the center of the receiving member 4, through which the impeller shaft 1 can pass and form a limiting structure with the other end of the limiting member; under the action of the elastic member or external force, the other end of the limiting member approaches the first through hole and connects or separates from the limiting groove at the end of the impeller shaft 1.

[0049] Under the action of the elastic element, the other end of the limiting element is connected to the impeller shaft 1 through the limiting structure, which plays an axial limiting role on the impeller shaft 1, realizing the connection between the fixed component and the impeller shaft 1, and then the impeller shaft 1 drives the impeller to rotate; specifically, the limiting structure can be a matching structure of limiting buckle and limiting groove; the limiting buckle is set at the other end of the limiting element, and the limiting groove is set at the end of the impeller shaft 1; or the limiting groove is set at the other end of the limiting element, and the limiting buckle is set at the end of the impeller shaft 1; the action of the elastic element makes the limiting buckle approach and maintain connection with the limiting groove, and then the fixed component is connected to the impeller shaft 1; the limiting structure can also be a matching structure of clip and clip groove; when an external force is applied to one end of the limiting element, the elastic element deforms, the limiting buckle moves away from the limiting groove and disengages from the impeller shaft 1, and then the impeller component and the fixed component are separated from the impeller shaft 1.

[0050] Preferably, a limiting groove is formed at one end of the impeller shaft 1, and a limiting buckle is formed at the other end of the limiting member. Under the action of the elastic member, the limiting buckle approaches and is engaged in the limiting groove, thereby limiting the axial movement of the impeller shaft 1. Combined with the insert 3, the impeller shaft 1 is limited in the radial and circumferential directions. The impeller assembly and the fixed assembly are driven to the impeller shaft 1. When the impeller shaft 1 rotates, the impeller rotates accordingly. When an external force is applied to one end of the limiting member, the elastic member contracts, the limiting buckle moves away from the limiting groove, and the impeller assembly and the fixed assembly separate from the impeller shaft 1.

[0051] <Fixed Components>

[0052] like Figure 1a , Figure 1b , Figure 2 , Figure 3 , Figure 4aand Figure 4b As shown, the fixing component provided in this embodiment includes a receiving member 4 and a limiting member. A supporting rib is formed on the top of the receiving member 4, and one end of the limiting member is connected to the supporting rib through an elastic member. The limiting member includes a first limiting member 51 and a second limiting member 52. Correspondingly, the supporting rib includes a first supporting rib 411 and a second supporting rib 412, and the elastic member includes a first elastic member 421 and a second elastic member 422. The first limiting member 51 corresponds to the first supporting rib 411 and the first elastic member 421, and the second limiting member 52 corresponds to the second supporting rib 412 and the second elastic member 422. They are disposed opposite to each other at both ends of the receiving member 4 and on both sides of the first through hole 46.

[0053] Specifically, the receiving member 4 is a cylindrical structure with a cavity at its top for accommodating the limiting member. The supporting rib extends upward perpendicularly to the top surface of the receiving member 4. One end of the first limiting member 51 is connected to the left side of the first supporting rib 411 via the first elastic member 421, and the other end extends to the right side of the first supporting rib 411 and to the first through hole 46. One end of the second limiting member 52 is connected to the right side of the second supporting rib 412 via the second elastic member 422, and the other end extends to the left side of the second supporting rib 412 and to the first through hole 46.

[0054] Preferably, at the first through hole 46, the other ends of the first limiting member 51 and the second limiting member 52 are staggered along the axial direction of the impeller shaft 1, correspondingly the impeller shaft 1 has a first limiting groove 11 and a second limiting groove 12, and the first limiting groove 11 and the second limiting groove 12 are staggered along the axial direction of the impeller shaft 1; the other end of the first limiting member 51 cooperates with the first limiting groove 11, and the other end of the second limiting member 52 cooperates with the second limiting groove 12; under the action of the first elastic member 421, the first limiting member 51... The other end of the component 51 is engaged in the first limiting groove 11. Under the action of the second elastic component 422, the other end of the second limiting component 52 is engaged in the second limiting groove 12, thereby realizing the connection between the first limiting component 51 and the second limiting component 52 and the impeller shaft 1. When the impeller shaft 1 rotates at high speed, the first limiting component 51 and the second limiting component 52 are staggered, which plays a good axial limiting role on the impeller shaft 1 and the limiting effect gradually increases with the rotation speed of the impeller shaft 1, thus preventing the fixed component from separating from the impeller shaft 1.

[0055] Specifically, the limiting member is a ring structure with a transition section extending from one end to the other, so that one end of the limiting member and the other end have different heights; the left end of the first limiting member 51 is higher than the right end of the first limiting member 51, and the right end of the second limiting member 52 is higher than the left end of the second limiting member 52. Correspondingly, the first limiting groove 11 and the second limiting groove 12 are respectively provided on the right and left sides of the impeller shaft 1, and the height of the first limiting groove 11 is lower than the height of the second limiting groove 12; the right end of the first limiting member 51 extends to the right side of the impeller shaft 1, and the left end of the second limiting member 52 extends to the left side of the impeller shaft 1; under the action of the first elastic member 421, the right end of the first limiting member 51 is engaged in the first limiting groove 11; under the action of the second elastic member 422, the left end of the second limiting member 52 is engaged in the second limiting groove 12.

[0056] Preferably, the top of the receiving member 4 is also provided with a sliding seat; the limiting member is slidably connected to the sliding seat, and when the elastic member or external force is applied to the limiting member, the limiting member can slide along the sliding seat, so that the limiting member moves along a fixed trajectory.

[0057] Preferably, the sliding seat includes a first sliding seat 431 and a second sliding seat 432, which are disposed opposite to each other at both ends of the receiving member 4 and on both sides of the first through hole 46; the first limiting member 51 corresponds to the first sliding seat 431, and the second limiting member 52 corresponds to the second sliding seat 432; under the action of the first elastic member 421 or an external force, the first limiting member 51 slides left and right relative to the first sliding seat 431; under the action of the second elastic member 422 or an external force, the second limiting member 52 slides left and right relative to the second sliding seat 432; when the first elastic member 421 acts on the first limiting member 51 and the second elastic member 422 acts on the second limiting member 52, the right end of the first limiting member 51 and the left end of the second limiting member 52 play a good axial limiting role on the impeller shaft 1; preventing the first limiting member 51 and the second limiting member 52 from tilting up and down, thus weakening the limiting effect on the impeller shaft 1.

[0058] Specifically, the first sliding seat 431 is fixedly connected to the upper right side of the first support rib 411; the second sliding seat 432 is fixedly connected to the lower left side of the second support rib 412.

[0059] Preferably, the side of the first elastic member 421 that mates with the first sliding seat 431 is provided with a groove or a slide rail, and correspondingly, the side of the first sliding seat 431 that mates with the first elastic member 421 is provided with a slide rail or a groove; the groove and the slide rail mate to realize the sliding of the first elastic member 421 relative to the first sliding seat 431.

[0060] The side of the second elastic member 422 that cooperates with the second sliding seat 432 is provided with a groove or a slide rail, and correspondingly, the side of the second sliding seat 432 that cooperates with the second elastic member 422 is provided with a slide rail or a groove; the groove and the slide rail cooperate to realize the sliding of the second elastic member 422 relative to the second sliding seat 432.

[0061] In this embodiment, the first elastic element 421 is provided with a slide rail, and the corresponding first sliding seat 431 is provided with a slide groove; the slide groove cooperates with the slide rail to realize the sliding connection between the first elastic element 421 and the first sliding seat 431; the second elastic element 422 is provided with a slide rail, and the corresponding second sliding seat 432 is provided with a slide groove; the slide groove cooperates with the slide rail to realize the sliding connection between the second elastic element 422 and the second sliding seat 432.

[0062] Preferably, under the action of the first elastic member 421, the first limiting member 51 slides relative to the first sliding seat 431 and approaches the first through hole 46, so that the right end of the first limiting member 51 is located on the right side of the impeller shaft 1, and then the right end of the first limiting member 51 is engaged in the first limiting groove 11; under the action of the second elastic member 422, the second limiting member 52 slides relative to the second sliding seat 432 and approaches the first through hole 46, so that the left end of the second limiting member 52 is located on the left side of the impeller shaft 1, and then the left end of the second limiting member 52 is engaged in the second limiting groove 12. Therefore, the first limiting member 51 and the second limiting member 52 play an axial limiting role on the impeller shaft 1. Combined with the circumferential and radial limiting of the impeller shaft 1 by the insert 3, the impeller shaft 1 can drive the impeller to rotate and wash clothes.

[0063] Preferably, when an external force is applied to the left end of the first limiting member 51, the first limiting member 51 slides relative to the first sliding seat 431 and moves away from the first through hole 46, thereby disengaging the right end of the first limiting member 51 from the first limiting groove 11; when an external force is applied to the right end of the second limiting member 52, the second limiting member 52 slides relative to the second sliding seat 432 and moves away from the first through hole 46, thereby disengaging the left end of the second limiting member 52 from the second limiting groove 12; when an external force is applied to one end of both the first limiting member and the second limiting member simultaneously, the impeller assembly and the fixing assembly can be separated from the impeller shaft 1.

[0064] Preferably, the side of the receiving member 4 is also provided with an operating position; the operating position includes a first operating position 441 and a second operating position 442; the first operating position 441 corresponds to the left end of the first limiting member 51; an external force is applied to the left end of the first limiting member 51 at the first operating position 441; the second operating position 442 corresponds to the right end of the second limiting member 52, and an external force is applied to the right end of the second limiting member 52 at the second operating position 442; specifically, when it is necessary to disassemble the impeller assembly and the fixing assembly, the left end of the first limiting member 51 and the right end of the second limiting member 52 are respectively applied by fingers, the right end of the first limiting member 51 is disengaged from the first limiting groove 11, and the left end of the second limiting member 52 is disengaged from the second limiting groove 12, and the impeller assembly and the fixing assembly are disassembled upwards.
